Usability is not often thought of as a criterion during the purchasing process. Moreover, unless you actually test a number of units in a realistic environment doing typical tasks, you are not likely to notice the ease or difficulty of use. [...] Do it right there in the store. Do not be afraid to make mistakes or ask stupid questions. Remember, any problems you have are probably the design's fault, not yours.

What I mean by 'thought' is the whole thing — thought, 'felt', the body, the whole society sharing thoughts — it's all one process. It is essential for me not to break that up, because it's all one process; somebody else's thought becomes my thought, and vice versa. Therefore it would be wrong and misleading to break it up into my thought, your thought, my feelings, these feelings, those feelings. I would say that thought makes what is often called in modern language a system. A system means a set of connected things or parts. But the way people commonly use the word nowadays it means something all of whose parts are mutually interdependent — not only for their mutual action, but for their meaning and for their existence. A corporation is organized as a system — it has this department, that department, that department... they don't have any meaning separately; they only can function together. And also the body is a system. Society is a system in some sense. And so on.
Similarly, thought is a system. That system not only includes thought and feelings, but it includes the state of the body; it includes the whole of society — as thought is passing back and forth between people in a process by which thought evolved from ancient times. Thought has been constantly evolving and we can't say when that system began. But with the growth of civilization it has developed a great deal. It was probably very simple thought before civilization, and now it has become very complex and ramified and has much more incoherence than before.
Now, I say that this system has a fault in it — a 'systematic fault'. It is not a fault here, there or here, but it is a fault that is all throughout the system. Can you picture that? It is everywhere and nowhere. You may say "I see a problem here, so I will bring my thoughts to bear on this problem". But "my" thought is part of the system. It has the same fault as the fault I'm trying to look at, or a similar fault.
Thought is constantly creating problems that way and then trying to solve them. But as it tries to solve them it makes it worse because it doesn’t notice that it's creating them, and the more it thinks, the more problems it creates.

After it is all over, as stupid a fellow as I am can see that mistakes were made. I notice, however, that my mistakes are never told me until it is too late, and you, and all my officers, know that I am always ready and anxious to have their suggestions.

Generally, (military) exercises not only contribute to the testing of professional skills and inter-operability of participating units and personnel, but also are a good opportunity for the units from various states, interested in the overall security and stability of our region, to develop combined operations and jointly implement given tasks as a team. Therefore Armenia has always been willing to host such events and open its welcoming doors to the participants by trying to provide for them the most comfortable working environment.

In the consumer economy taste is not the criterion in the marketing of expensive soft drinks, usability is not the primary criterion in the marketing of home and office appliances. We are surrounded with objects of desire, not objects of use.

The fine-tuning of the universe, about which cosmologists make such a to-do, is both complex and specified and readily yields design. So too, Michael Behe's irreducibly complex biochemical systems readily yield design. The complexity-specification criterion demonstrates that design pervades cosmology and biology. Moreover, it is a transcendent design, not reducible to the physical world. Indeed, no intelligent agent who is strictly physical could have presided over the origin of the universe or the origin of life.
